Paige invested 1200 at an interest rate of 5.75% compounded quarterly. Determine the value of her investments in 7 years.

iragen [17]

Use the formula A=p(1+r)^n
where
A= value of investment
r= rate
n= time period
p= amount invested
in this question
r= 5.75% but compounded quarterly means divide this by 4
r= 23/1600
n=7*4
n=28
p= $1200
A=1200(1+23/1600)^28

A= $1789.54

Therefore the value of her investment in 7 years is $1789.54

mote1985 [20]

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed $V_{avg}=10km/h$

Distance traveled $d=7km$

Generally the velocity across a distance is mathematically given given as $V=d/t$

$10=\frac{7}{t}$

$t=0.7h\\t=42minutes$

Therefore

7:20-42 minutes =6:38am

worty [1.4K]

<u>Answer:</u>

The ratio of African Americans to Hispanics Americans present is 16 : 5

<u>Explanation:</u>

Given the people attending the soccer game were:

2800 among them are Caucasians

4800 are African Americans

1500 are Hispanics

And, 1400 of those were from other ethnic backgrounds

We have to find the Ratio of African Americans to Hispanics Americans

Therefore,

African Americans : Hispanics Americans = 4800 : 1500

$\frac{\text { African American }}{\text { Hispanics American }}=\frac{4800}{1500}=\frac{48}{15}=\frac{16}{5}$

Hence, the ratio of African Americans to Hispanics Americans present in the ratio were 16 : 5
